  • Modulation method for diode-laser pumped lasers
    Patent number: 8351477
    Abstract: A method of operating a digitally modulated solid state laser is disclosed. The laser is optically pumped by a current-supply driven diode-laser radiation and with output-power stabilized at a desired value by a light regulator cooperative with a power monitor and the current source is disclosed. When the laser is turned on, the current-source is enabled and the light-regulator is disabled. A current regulator allows current from the current-supply to increase until the monitored power reaches the desired value. At this point, the light regulator is enabled and the light regulator assumes control of the current-supply for maintaining the output-power at the desired level.
